I have a 98 buick park ave and the right turn signals dont work both front and back quit at the same time and it dont blink on dash either.
the left ones work great. any help would be greatly app.

Should the tail light bulbs burn out, the dash light directional arrow will only light up, but not blink. You may just have burnt out lightbulbs.

the right indacater light on the dash dont light up either

the flashing coil/relay maybe?

Try putting the emergency flashers on and that will indicate if a lamp is out,replace any and check again,Also check side markers.
